Healthy diets spark lung cancer risk in non-smokers as pesticides loom

A study led by Dr. Jorge Nieva of USC Norris Comprehensive Cancer Center found a link between healthier diets rich in fruits, vegetables, and whole grains and increased lung cancer risk in non-smokers under 50. Researchers hypothesize that pesticides on conventionally grown produce may contribute to this association, though the study is observational and not peer-reviewed.
